We AVOID These Common Ingredients in our Liquid D3: Bulking Agents: Used to increase volume but offer no nutritional value and can lead to digestive issues. We skip unnecessary fillers to keep our product clean¹. Anti-Caking Agents (e.g., Magnesium Stearate): Commonly used to prevent clumping and speed up production efficiency, but it may affect nutrient absorption and irritate the gut in sensitive individuals². Animal-Derived D3: Animal-derived D3, like from sheep’s wool (lanolin), is less sustainable and artificial. We use plant-based D3 from sustainable pine, which is equally effective and ethical³. Third-Party Lab Testing: Unlike many brands that skip third-party testing because it’s not required by law, we go the extra mile to ensure our products are pure and safe. We rigorously test both our ingredients and final formulas for heavy metals, pesticides, and contaminants, giving you confidence that what you’re putting in your body is clean and trustworthy⁴. We back up our claims with full nutritional analyses on every product, ensuring you can trust what you’re putting in your body.
